"Variation of proof #43 - Pythagorean Theorem"
 
   OK, here is yet another one I have done. I have not seen anything like this exactly on your page, but I feel it is a variation somewhat of proof #43, which is my favorite of the proofs that are on the page...

Here it is:

   The word "quadrilateral" is spelled "quadrlatral" in the addition you made to proof 43.

   Regarding your final comment on proof #43, I was not sure if you had seen this page:

https://demonstrations.wolfram.com/MamikonsProofOfThePythagoreanTheorem/

It has a nice animation and the final statement about the PT is an image on this page as well:
